We divide 763079 by 77
The aim is to understand the frequency of 77 in 763079.

Let's proceed to step 1:
77 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 77

Let's proceed to step 2:
If we divide 76 by 77, we get 0 and a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Take the next digit (3) from the dividend and append it to 76, then repeat: 763 / 77

Step 3:
77 goes into 763 9 times with a remainder of 70.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 693 from 763 to get 70.
Grab the next digit (0) from the dividend, add it to 70, then carry on: 700 / 77

Step 4:
The number 77 fits into 700 9 times, leaving a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
Subtracting 693 from 700 leaves us with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 77

Step 5:
The number 77 fits into 77 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 991.0
Deduct 77 from 77 and we're left with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 77

Advancing to step 6:
The number 77 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 9910.0
If we take 0 away from 9, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
When dividing 90 by 77, we get 1 with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 9910.1
If we subtract 77 from 90, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 8:
When dividing 130 by 77, we get 1 with a remainder of 53.
The number 1 becomes the next digit in our result. 
Result so far: 9910.11
Subtracting 77 from 130 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

The final result is 9910.11 with a remainder of 0.053.
